As an alternate, Saybolt-Furol aaashto may be specified as follows: Standard naphtha Naphtha-xylene solvent, percent xylene Heptane-xylene solvent, percent xylene 30 38 — 60 — 0. A material used to hold solid particles together, i. Consistency can be further modified by air blowing.

Properties of Asphalt Important properties of asphalt include: Aggregates Usually refers to a soil that has in some way been processed or sorted. In order to attain workable asphalt cement at ambient temp. Distillation used in Cutback asphalt Loss on heating: Asphalt is liquefied by two methods: The flash point is the temperature at which a small blue flicker around the inside of the cup is seen as the wand is passed horizontally over the surface of the cup.
Bitumen is soluble in carbon disulfide. Loss on heating Thin film oven test Flash point. F is more than To make asphalt workable soften it should be heated. An example would be a finished. F Residue from distillation to ? A 50 g sample of asphalt is poured into each of three flat-bottomed pans.
Penetration is found for aged samples. Air blowing is used to increase viscosity of asphalt residue. However, in no case will both be required. Dissolve Cut the asphalt in solvent. AC heated at specified rate. F See Note 2. F is less thanthe material will be acceptable if its ductility at Flames pass across the surface. Solubility in Trichloroethylene, percent Spot test See Note 4. If you wish to download it, please recommend it to your friends in any social system.
M 1. Auth with social network: The aged samples are then combined into one container, mixed, and used to determine the aged asphalt cement properties. The emulsion stay in this stable situation until disturbed by: F — to s.
In lieu of viscosity of the residue, the specifying agency, at its option, can specify penetration at g, 5 s at 25? Grade MC—Furol viscosity at 50? Used to separate volatile from nonvolatile substances. The use of the spot test is optional.
